HENRY J. RELYEA, OF RICHMOND, INDIANA, ASSIGNOR TO HENRY 0. FOX, OF SAMEPLACE.

WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 262,117, dated August1, 1882.

Application filed June 21, 1882. (No model.)

To all whom it may concern Be it known that I, HENRY J. RELYEA, ofRichmond, Wayne county, Indiana, have invented a new and usefulImprovement in Wind-Engines, of which thefollowingisaspecification.

My invention relates to the class of wind mills or engines whosewind-wheel shaft and vane or rudder are capable of simultaneous 1o veeror swing about a vertical pivot common to both, and also capable, underthe influence of a sudden gust, of a relative change in position, inwhich the wind-wheel assumes a position parallel or approximatelyparallel to the rudder, so as to feather said wheel, and thus bothprevent its destruction and that of the machinery driven by it.

My improvements are directed to devices for moderating or checking bothexcessive veloc- 2o ity of rotation of the wind-wheel and a too violentor concussive folding of the wind-wheelframe against the rudder or vaneframe, and for facilitating the return of the parts to their normalpositions.

In the accompanying drawings, Figure l is a rear elevation of awind-engine embodying my invention, the same being shown in its normalcondition. Fig. 2 is a top view of the adjacent portions of the rudderand wind-Wheel 3o frames,a1soin thenormalcondition. Fig.3isa

perspective view of the same in the folded condition. Fig. 4 is ahorizontal section of the same, on a larger scale, in a partly-foldedcondition. Fig. 5 is a top view of my wind-wheel brake mechanism in itseffective condition.

A may represent the top portion of a column or trestle, from whosemetallic cap B rises a vertical stud or post, 0, which serves as thepintle or pivot of two horizontally-swinging frames, D E, of whichframes the frame D extends rearward to form the vane or rudder F, andframe E contains thejournal-bearings G of shaft H of my wind-wheel I.These parts are held to normal position by customary wing or governor,J, connected by crank K and rod L with wind-wheel frame. A blade, M,upon the extremity of the governor, in case of any sudden or violentgust of wind, elevates said governor, and, through crank K and rod Laforesaid, draws the wind-wheel into a greater or less approach toparallelism with the vane according to the stress of the wind. All ofthe above features are old and well known.

In order to moderate the violence of folding action of the wind-wheelframe upon the tailvane, and to prevent destructive concussion of theparts, and to facilitate their return to the normal condition, I give toa portion, N, of my vane-frame a cam-formed or eccentric contour andpivot on the wheel-frame an arm, 0, having a roller, (1, which is causedto hear forcibly on the said cam-periphery by a strong spring, P. Thisarrangement of parts operates cushion-like in opposing agradually-increasing resistance to the folding together of the vane andwind-wheel frames, and thus averts the destructive collisions to whichthese important members are ordinarily subject.

In order to avoid the almost equally objectionable excessive velocity ofrotation of the wind-wheel in high winds, I give the wheel Q at the heelof the wind-wheel shaft the bevel form shown, and I provide a spring, R,upon a bracket or projection, S, upon the vane-frame, whose impingementagainst the chamfered pe- 7 riphery of the wheel Q operates as a braketo retard and modify the rotation of the windwheel, and also operates asan auxiliary to the members N O P in softening the shock of the foldingframes.

The above-described preferred form of my invention may be modified innon-essential particulars. For example the roller 0 may be omitted fromthe pressure-arm 0, and the end of said arm may press directly againstthe 8 5 cam-surface. The pressure-arm may belocated on the vane-frameand coact with a cam-surface upon the wind-wheel frame. A simple diskmay replace the bevel-wheel Q.

I do not claim a cushion or spring bumper 0 or brake to avert concussionin a wind-engine, such devices being old and well known.

I claim herein as new and of my invention- 1. In a wind-engine havingsimultaneously and independently veering vane and wind- 5 wheel framesand governor-wing, the cam N upon the vane-frame, in the describedcombination with arm (),and springP upon the windwheel frame, for thepurpose set forth.

2. In a. wind-engine whose vane and windwheel are on jointed framescontrolled by gravitating governor-wing the combination, with brakemechanism consistingof whcelQ, spring R, and projection S, of the cam oreccentric N, constituting a rigid projection from the vaneframe, and thepivoted arm 0 and spring 1 [0 upon the wheel-frame, substantially as andfor the. purpose set; forth.

In testimony of which invention I hereunto set my hand.

HENRY J. RELYEA.
